  • Patent number: 9286700
    Abstract: A method for acquiring a PET image with ultra high resolution using movement of a PET device is provided. In the related art, there is a limit in lowering of the resolution below a half (d/2) of the width of a detector. According to the provided method, an image with ultra high resolution, which can jump over the limit, can be acquired. Further, since utilization of larger detectors becomes possible without a loss of the resolution, the sensitivity of the PET can be improved, and thus an image of higher quality can be acquired.

  • Publication number: 20150297120
    Abstract: The present invention relates to a method for tracking the motion of a subject in real time and for correcting a medical image. The method includes the steps of: (a) a motion detection module outputting real-time motion information of a subject; (b) a motion calculation module receiving and analyzing the real-time motion information, transforming the analyzed result into triaxial motion parameters, and outputting the triaxial motion parameters; (c) a driving module driving a driving motor in response to the triaxial motion parameters; and (d) a medical image data acquisition module moving by as much as the subject moves in response to the driving of the driving motor. According to the present invention, medical image data can be acquired as if a subject has not moved during imaging by calculating the triaxial motion parameters of a subject through motion information acquired from the motion detection module and moving the medical image data acquisition module according to the triaxial motion parameters.

  • Patent number: 7541916
    Abstract: A power supply using a static magnetic field of a tire pressure monitoring system is provided. The power supply includes: a static magnetic field generator installed at a car position adjacent to a tire, and generating the static magnetic field; and an EMF (ElectroMotive Force) coil installed at the tire, and generating an induced electromotive force by the generated static magnetic field and a relative motion resulting from rotation of the tire, and providing the generated electromotive force to the transmitter and the sensor.

  • Patent number: 7081868
    Abstract: The present invention relates to a reception antenna structure of a tire pressure monitoring system. The reception antenna is implemented using a cable-type antenna connected to a receiver of the tire pressure monitoring system. The cable-type antenna enables a mounting position of the antenna to be freely changed and improves a reception rate for measured data about temperature and pressure of a tire, that is modulated into data in the UHF band and transmitted to the outside of the tire in a wireless manner by a transmitter.
